Abstract
Abstract A portable personal cooling apparatus comprising: an exterior surface of fibrous material having a fluid holding capacity sufficient to allow continuous evaporation of a fluid; an interior surface of waterproof material adapted to avoid wetting of the object to be cooled from the fluid on the exterior surface; a fluid container on one of said surfaces for distributing the fluid to the fibrous material; a fluid collector on one of said surfaces for collecting the accumulated unevaporated fluid; at least one fluid return line for moving fluid in the fluid collector to the fluid container; and at least one of said return lines further including means for preventing fluid from flowing back from the fluid container to the fluid collector.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
134 words
Personal cooling apparatus comprising: an exterior surface of fibrous material having a length dimension and a fluid holding capacity sufficient to allow continuous evaporation of the fluid; an interior surface of waterproof material, having a continuous length the same as the exterior surface, adapted to prevent the object to be cooled from being wetted by fluid on the exterior surface; at least one elongated tubular fluid container positioned at an edge of said fibrous material, comprising means for distributing fluid to the fibrous material via an edge thereof, said fibrous material extending into the fluid container; at least one fluid collector means associated with one of said surfaces, for collecting accumulated unevaporated fluid; at least one return line means for moving the fluid in the fluid collector to the fluid container by gravitational force.
Claim 2
Dependent Claim
134 words
Personal cooling apparatus comprising: an exterior surface of fibrous material having a length dimension and a fluid holding capacity sufficient to allow continuous evaporation of the fluid; an interior surface of waterproof material, having a continuous length the same as the exterior surface, adapted to prevent the object to be cooled from being wetted by fluid on the exterior surface; at least one elongated tubular fluid container positioned at an edge of said fibrous material, comprising means for distributing fluid to the fibrous material via an edge thereof, said fibrous material extending into the fluid container; at least one fluid collector means associated with one of said surfaces, for collecting accumulated unevaporated fluid; at least one return line means for moving the fluid in the fluid collector to the fluid container by gravitational force.
Claim 3
